title: Efficient panchromatic organic sensitizers with dihydrothiazole derivative as π-bridge for dye-sensitized solar cells.
abstract: Novel organic dyes CC201 and CC202 with dihydrothiazole derivative as π-bridge have been synthesizedand applied in the DSSCs. With the synergy electron-withdrawing of dihydrothiazole and cyanoacrylic acid, these two novel dyes CC201 and CC202 show excellent response in the region of 500-800 nm. An efficiency as high as 6.1% was obtained for the device fabricated by sensitizer CC202 together with cobalt electrolyte under standard light illumination (AM 1.5G, 100 mW cm(-2)). These two novel D-π-A panchromatic organic dyes gave relatively high efficiencies except common reported squaraine dyes.
